quick question. I know i can re-use arp head studs if they are within spec, but if i torqued down a brand new oem head gasket between a machined head and block and i need to take the head back off, would i be able to reuse the head gasket? no, the engine hasn't been started.

Since you haven't started it POSSIBLY, but I would DEFINATELY copper spray it. Biggest question is though what brand head gasket?Style? etc. if its Fel-Pro just go warranty. lol

Don't copper spray anything, and you can reuse the gasket if it was only torqued down and not heat cycled. Copper spray will only cost extra money and won't stop a leak from happening, as long as everything is straight it will seal.

Hmm... torqued it to 60 ft lbs? I think the correct question to ask you is... Would you be willing to take it back apart if it doesn't work? If not, then go get a new one. If yes, then we all will know the answer to your question in about 150-300 miles if it does or doesn't over heat. I personally never reused gaskets, never works out well for me. I wouldn't want to do it if it was me. Just the gasket isn't that expensive and certainly not worth the frustration of being stranded possibly on the highway somewhere..

Don't copper spray? lol okay :) it transfers heat and it makes it able to handle more heat. Ask me how I know? ive done it, lets you be bale to run it hotter before it starts to leak. I guess its preference. I live by it on new gaskets. Theres even other threads where other people swear by it. $6 for a can of copper spray. $6 is worth the extra reassurance to me.

That spray is great for metal gaskets that dont have a viton seal.


Honda Gaskets have a viton seal which does a damn good job of holding together.


but, its your engine, do what you like.

It'll be fine if it hasn't been heat cycled. I've asked the same question, got the same answer, did the same thing, and never had an issue.

Believe Bone even re-used a heat cycled gasket before and didn't have any leaks.

cool, thanks for the feedback! Also talked to my buddy that's a tech at Honda for some years now that's built boosted engines on the side. Said its cool to re-use it. He even mentioned he's used one that's ran for just a couple miles and re-used and had no problems. But also, using a heat cycled one is up to you of course and may not yield the same results.

Always heard no.
There tq gasketes. You tq them and they flatten out/crush more.
I wouldnt reused one even if there wasnt any heat cycles.

And copper spray isnt really needed on these gasket.
I use it before without problems. But its not needed so i stop using it.
